２５例无痛性心肌梗塞与５９例伴有胸痛的心肌梗塞患者临床分析比较后表明，无痛性心肌梗塞的临床特征有：（１）年龄大（５９．９岁与６８．８岁，Ｐ＜０．０１）；（２）合并症多，以心房纤颤，特别是合并神经精神疾恶、糖尿病、呼吸系感染更显著（Ｐ＜０．０１）；（３）ＥＣＧ以前壁梗塞、无Ｑ波型梗塞多见（Ｐ＜０．０５），但梗塞范围较对照组小，≥２个部位者仅３６％（对照组６１％，Ｐ＜０．０５）；（４）入院误诊率高（４８％：１５．３％，Ｐ＜０．０５），但住院病死率显著低于对照组（８％：３４％，Ｐ＜０．０１）。
The clinical analysis of 25 patients with painless myocardial infarction and 59 patients with myocardial infarction complicated with chest pain showed that the clinical features of painless myocardial infarction were: (1) older (59.9 and 68.8 years, P (P <0.01); (3) The anterior wall infarction of the ECG, no significant difference between the two groups Q wave infarction was more common (P <0.05), but infarct size was smaller than that of the control group, only 36% of ≥2 sites (control group, 61%, P <0.05); (4) (48% vs 15.3%, P <0.05), but the in-hospital mortality rate was significantly lower than that of the control group (8% vs 34%, P <0.01).
